Sometimes it feels like a solution to not using a proprietary program, is not to use software, but rather delegate the computing to some server somewhere on the internet. But that does not fix the underlying issue. Your computing is still done with software that you don't control. Even if SaaSS is implemented with Free Software, it's not enough. Since you can't possibly ask to control the server.

It's not SaaSS though, if the service is meant to exchange information between users. Like email. It's SaaSS when this computation would be possible to make ( even if perhaps slower ) on your own machine, if the software was available to install and run. Something like ChatGPT or Google Translate are SaaSS.
